Question
Consider the following Statements. (1) Ozone
depletion refers to the phenomenon of reductions in the amount of ozone in the stratosphere. (2) The problem of ozone depletion is caused by high levels of chlorine and bromine compounds in the stratosphere. (3) Ozone depletion is an irreversible phenomenon. Which of the above statement(s) is/are CORRECT?Solution
Ozone depletion refers to the phenomenon of reductions in the amount of ozone in the stratosphere. The problem of ozone depletion is caused by high levels of chlorine and bromine compounds in the stratosphere. The origins of these compounds are chlorofluorocarbons (CFC), used as cooling substances in air conditioners and refrigerators, or as aerosol propellants, and Bromo fluorocarbons (halons), used in fire extinguishers. As a result of depletion of the ozone layer, more ultraviolet (UV) radiation comes to Earth and causes damage to living organisms. UV radiation seems responsible for skin cancer in humans; it also lowers production of phytoplankton and thus affects other aquatic organisms. It can also influence the growth of terrestrial plants.
